Which method of distress signalling is most likely to gain the attention of other boaters in the area who may be able to assist you?

The most effective method of distress signaling to gain the attention of other boaters is the use of flares, particularly hand-held or parachute flares. These devices produce bright light and smoke, making them easily visible over long distances, even during the day. Additionally, using a VHF radio to send out a distress call on channel 16 can alert nearby vessels to your situation. Combining visual signals with radio communication increases the chances of getting timely assistance.
